Lenovo on Monday showed off a laptop with a foldable screen and one that can get extra battery life from solar power. These laptops are just concepts, meaning they are not commercially available. Lenovo, the world's biggest PC maker, has a history of showing off imaginative concepts with some becoming reality, so it's worth keeping an eye on what the Chinese technology giant is up to. For example, Lenovo previously showed off the idea of a rollable laptop — one where the screen rolls upwards to increase the size of the display. The company will begin selling such a laptop this year.

Crowds gathered in a Vermont town on Saturday to protest Vice President JD Vance's visit to a local ski resort, the day after his explosive Oval Office clash with Ukrainian President Volodymyr Zelenskyy. Protesters lined a main thoroughfare in Waitsfield, Vermont, located near the Sugarbush Resort where Vance and his family were vacationing. They held signs that said, "Vance is a traitor go ski in Russia," "Trump serves Putin" and "Vance disgraces our country," among other fiery messages. A small group of protesters also gathered at the Sugarbush Resort, though a spokesperson for the resort said it was largely a "smooth day overall" at the slopes.

Treasury Secretary Scott Bessent said Sunday that President Donald Trump's proposed tariffs are unlikely to raise inflation, in part because China will "eat any tariffs that go on." Bessent's comments come just two days before the tariffs are scheduled to go into effect on Tuesday. Trump is expected to impose 25% tariffs on imports from Mexico and Canada. The president also announced the U.S. would impose an extra 10% duty on Chinese imports, on top of the 10% tariff he levied on the country on Feb. 4. Some economists have raised concerns about the possibility that the tariffs could lead to an increase in inflation and keep interest rates elevated into 2026.

Legendary investor Warren Buffett made a rare comment on President Donald Trump's tariffs, saying punitive duties could trigger inflation and hurt consumers. "Tariffs are actually, we've had a lot of experience with them. They're an act of war, to some degree," said Buffett, whose conglomerate Berkshire Hathaway has large businesses in insurance, railroad, manufacturing, energy and retail. He made the remarks in an interview with CBS News' Norah O'Donnell for a new documentary on the late publisher of the Washington Post, Katharine Graham. "Over time, they are a tax on goods. I mean, the Tooth Fairy doesn't pay 'em!" Buffett said with a laughter. "And then what? You always have to ask that question in economics. You always say, 'And then what?'"

Cryptocurrencies rallied on Sunday after President Donald Trump announced the creation of a U.S. strategic crypto reserve that will include bitcoin and ether, as well as XRP,  Solana's SOL token and Cardano's ADA, he said in a post on Truth Social. "A U.S. Crypto Reserve will elevate this critical industry after years of corrupt attacks by the Biden Administration, which is why my Executive Order on Digital Assets directed the Presidential Working Group to move forward on a Crypto Strategic Reserve that includes XRP, SOL, and ADA," the post said. "I will make sure the U.S. is the Crypto Capital of the World." "And, obviously, BTC and ETH, as other valuable Cryptocurrencies, will be at the heart of the Reserve," he said in a follow-up post.
